> Summary: 
> Don't use Tomcat versions 5.5.10 - 5.5.15 with Wicket 6, these versions of Tomcat will not cleanup the page filestore after sessions are invalidated.
> Details:
> I upgraded an application running on an older version of Tomcat 5.5.12 to Wicket 6 and the WicketApplication-filestore page store no longer cleaned itself up anymore when sessions expired.
> This would have eventually caused the server to run out of disk space if left long enough.
> I tracked the cause of the Sessions not being cleaned up to the following:
> An illegal state exception is thrown in the specified versions of Tomcat 5.5 when the session.getId() is called in the HttpSessionStore.
> Apparently this is due to Tomcat invalidating the session before notifying all of the SessionBindingListeners and an implementation of a draft servlet spec to throw an IllegalStateException.
> The exception occurs in the cleanup code:
> HttpSessionStore$SessionBindingListener.valueUnbound(HttpSessionStore.java:465) 
> where it throws an illegal state exception when checking the "getId()" method of the Session.
> Tomcat versions 5.5.10 - 5.5.15 apparently implemented a portion in the draft of the servlet spec which specified getId() to throw an illegal state exception if the session was already invalidated.
> (see https://issues.apache.org/bugzilla/show_bug.cgi?id=36994 for details)
> This getId() ISE portion of the servlet spec was removed in the final servlet spec version because of the problems it caused in lots of cleanup code.
> Not really expecting Wicket to implement a fix, but I thought I would document this behavior in case anyone else happens to still run an older Tomcat 5.5 server with an affected version.
